The following steps will ensure that IOA has the libraries it needs in order to operate:

1. Add the following DAPARM DD statement to the IMS/DC procedure:

   //DAPARM   DD DISP=SHR,DSN=ilprefa.PARM

   //         DD DISP=SHR,DSN=ilprefa.IOAENV

2. If the IOA LOAD library is not included in the linklist, add it to the list of STEPLIB libraries.
